ELECTRIC RAI Lw A Y-slG NAL.

SPECIFIGATION forming part of Letters Patent No. 414,645, dated November 5, 1889. Application filed March 15, 1887. Serial No. 230,975. (No model.)

To (bZZ whom it may concern.-

Be it known that LWILLIAM P. KOOKOGEY, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Electric Railway- Signals, of which the followin g is a specification.

My invention relates to railwaysignals, and is designed more particularly for tunnels, deep cuts, and like places where trains are more or less hidden from view, though the invention is susceptible of general application as well.

Briefly stated, the invention consists in electric circuits which are closed or completed through the medium of the locomotive or train, and when completed cause an electric signal-light to be lighted at the entrance of the tunnel or out, which causes other lights to be successively lighted and extinguished as the train moves through the tunnel or cut or over the road to light its passage, and through which finally the signal-light is extinguished when the train completes its travel over the guarded section.

. The annexed drawingor diagram illustrates the arrangement of circuits and appliances therein for carrying my invention into prac' tice.

nected by a wire or conductor 5 to a wire or conductor D running parallel with the track.

From the conductor D branches 0 d c f run.

to the sections 1-2 3 4 of rail B, each branch containing an electric light E E E &c., of suitable size and character. From the poles of battery 0 two other wires g h proceed, one to a swinging or movable armature F and the other to a contact-block G,with which the armature makes connection when moved in one direction, thus completing a second circuit for battery G, passing through or including a signal-lamp H, introduced into wire 9.

J to line D, and another wire Zruns therefrom to section 4 of'rail B, the wires in each case of course connecting with opposite ends of the helix-wires of the magnets.

From the foregoing description it will be seen that if a locomotive or train approaches the cut or tunnel in the direction of the arrow and enters upon section 1 of rail B the wheels and axle at once bridge the rails A B and the electric circuit is completed from the positive pole of battery 0 through wire a, rail A, the wheels and axle of the locomotive or cars, wire 0, conductor D, and wire I), the circuit thus passing through light E in wire O and causing it to becomeluininous. At the same time the circuit passing through Wire a, rail A, the wheels and axle of the locomotive or cars to rail B traverses wire j, dividing between it and the wire 0, goes through the coils of magnet I, thence through wire 1', line D, and wire I) back to battery 0. By thus completing the circuit, which includes magnet I, said magnet is'energized and at once caused to attract armature F, which is thus brought into contact with block G, the magnet I being thus placed in multiple arc with lamps E E duo. This contact completes the second circuit of battery 0, (or it' may be an independent battery, if desired,) the current going through line g, block G,

armature F, wire 72-, and battery C, passing through the lamp H in wire 9 and rendering it luminous.

If it be desired to render lamp II more brilliant than lamps E E &c., it may be made of lower resistance; or two lamps of the same resistance maybe employed in multiple arc. If in multiple are, as above recited, magnet I should be of high resistance as compared with the lamps E E &c., so that the lamp may not be appreciably affected by the current passing through the magnet; but if arranged in series the magnet s'hould'be of as low resistance as practicable. Armature F, being arranged to swing in a horizontal.

5 plane and having no spring or other device to hold it in any particularposition, of course remains at rest in any position to which it may be adjusted. As the locomotive ortrai'n I leaves section 1 of rail B, wire and the first [0 cut out of the battery-circuit because 'the rails are no longer bridged within that seclamp E, as also wires 2' j and magnet I, are;

rial. This I do not claim.

As stated at the outset, my invention,

I am also aware that it has been proposed to combine with a railway-track a separate electric circuit having one main and two parallel branches, and rotary s'witchesat the side of'th'e -track designed to be turned by a passing train to complete and break the branch circuits successively. I This I likewi e-disclairn. Not only doesit needlesslyi lfi l'fi'ply conductors, buta switch of thejc'haracter mentioned is ,very unreliablafor the son that it 'i's liable to be thrown past itsproper position by fast-moving train if I s k fairly and properly; but even more so be use of thelateral play allowed the trucks of fan ordinary railway-train, whichby actual inc-asurernentisfound to be 'fi'omfone and aIhalf a; twoand a half in'che's, toj providefor which thetreads of the wheels are made wide.

This I also disclaim, except as to the particularplan I I Z abovedescribed, in which lamps are employed I" n aware that prior to my invention rail-i racks have been divided into insulated and the use of, switches, electro-jmagnets,jar-

a second battery-circuit containing a signallamp and having said circuit-closer introduced into and constituting a part of the cir cuit, all substantially as set forth.

3. In combination with a battery or equivalent source of electrical energy and a circuit therefor, comprising a continuous rail and a divided or sectional rail of the same track, electric lights introduced into said circuit, two electro-magnets in circuit with said lights, but having their circuits completed through different sections of the divided rail, a second circuit containing an electric signal-light, an armature situate between the two electromagnets and constituting a part of the second circuit, and a contact-block also constituting a part of said circuit, all'substantially as described and shown, whereby the passage of a locomotive or train along the track is caused to light the first lamp of the series and the signal-lainp, to extinguish the first and light the second lamp of the series, and so on to the end thereof, and finally to extinguish the last light of the series and the signal-light.

In combination with a continuous rail and a divided or separated rail, a battery or its equivalent having one pole connected with the continuous ma and the other pole connected with two separate sections of the divided rail, two electro-magnets connected with the battery through said continuous and divided rails, a second electric circuit, an
